The heater core on my '96 960 needs replacement. The normal Volvo sites I use to order parts only list the Nissens with plastic end tanks. Went to rock auto and they show 3 all aluminum heater cores. None of the 3 were brands I was familiar with. After considerable thought and against my better judgment I still ordered the plastic tanked Nissens heater core. Has anybody used the Nissens and are you happy with your decision? I was really torn with which brand to use. I went with the Nissens hoping the quality of the heater core is as good as their radiators. Thanks Dave
